The present invention pertains to a novel illuminating device designed especially for flood lighting of various indoor and outdoor areas such as halls, factories, arenas, airports, railroad yards, athletic fields, streets and the like.

One of the objects of the invention is to provide a device of this character capable of carrying various sizes of lamps. in keeping with its various uses. Inasmuch as the lamps vary in dimensions according to, wattage, it is a problem to maintain the various sizes of lamps in proper focus. Accordingly, the invention provides a means for adjusting the lamps in their reflectors.

This means consists essentially of a plate adjustably mounted in the lamp housing and carrying the lamp receptacles. The latter extend through another plate that carries the reflectors. Simple manual means are provided for shifting the first plate at will, whereby the lamps may always be positioned and focused regardless of Size.

I Another object of the invention is'to ventilate the lamp housing in a simple and effective manner. Th housing is formed with vents at front and rear, preferably located at top and bottom, and these vents are screened to prevent entrance ofinsects. The previously mentioned plates are also ported to permit circulation, and such circulation is induced by a fan mounted near the inlet opening.

The invention is fully disclosed by way of example in the following description and in the accompanying drawing in which:

Figure l is a vertical section of the device;

Figure 2 is a perspective view thereof;

Figure 3 is a front elevation;

Figure 4 is a section on the line 4-4 of Figure 3; Y

Figure 5 is a detail elevation of the reflector assembly plate;

Figure 6 is a detail section on the line 6-6 of Figure 3, and

Figure 7 is a detail vertical section at the bottom of the lamp housing.

Reference to these views 'will now be made by use of like characters which are employed to designate corresponding parts throughout.

In Figure 2 the housing I is shown as having cross braces 2 at its vertical end walls for the purpose of carrying the horizontal pivot pins 3. These members are received in the ends of a yoke I fitted in an adjustable socket member Ii. The latter is adapted to be secured on a suitable platform or tower. In the case of a platform of sub- 7 stantial area, additional support is obtained by lowering a pair of legs I adiustably mounted on the ends of the housing I by means of screws I.

On the bottom of the housing is mounted a terminal box 8 where the power lines 3 enter. 0n the rear wall of the housing and directly over the terminal box is provided an access door i3.

Vertically mounted in the housing and spaced from each other are a receptacleplate II and a reflector late, H. The former is formed with ear flanges I! (Figure 4) engaging the end walls ll of the housing. These walls are slotted horizontally at it to receive bolts i6 extending from the flanges It. The outer ends of the bolts are fltted with nuts i1. Thus, the plate II is adjustable horizontally in the housing for a purpose that will presently be described. This plate carries lamp receptacles i8 extending through openings is in the plate l2 and is provided with support slide bracket i8. 7

In these openings H are mounted reflector holders, preferably spherical, each consisting of a body or shell 20 from which extends a neck 2| into the corresponding opening IS. The free end of the neck is spun or flanged at 22 and split at 23, as shown'in Figure 5, for engaging the rear surface of the wall i2 and is attached thereto .by rivets or other suitable means. In

each shell 20 is fitted and secured a similarly -vents 32, and the lower end carries a handle 33 for lifting. Lock nuts 33 are used for flxing frame 30.

An opening 34 is formed in the bottom of the housing I and covered by a screen 35 held by screws 36, as shown in Figure 7. The rear wall of the housing carries an electric fan 31, with suitable electric connections thereto. The fan draws air through the opening 34 and discharges it through opening I! and ports 33 in the walls II and i 2. The air is driven forwardly between the reflector holders 20 to cool the same and is finally discharged through vents 32. The screens on the vents 32 and on the opening 34 prevent the entrance of insects.

Inasmuch as the device is designed for a variety of uses and for various sizes of lamps it is desirable to maintain the lamps in proper focus regardless of size. For this reason the receptacle plate H is adjustably mounted as previously stated. The plate is formed with rearwardly extending tapped bosses 39, as shown in Figure 4. Screws 40 are passed rotatably through the plate 12 and threaded into the bosses 39. Thus, when the nuts H are loosened, the plate ii can be adjusted by turning the screws 40. The position of the lamps in their reflectors is thereby adjusted.

Although a specific embodiment of the invention has been illustrated and described, it will be understood that various alterations in the details of construction may be made without departing from the scope of the invention as indicated by the appended claims.

What I claim is:

1. In an illuminating device, an open front housing, a plate mounted therein and adjustable from front to rear of said housing, a reflector plate forward of the first plate, reflectors carried by said reflector plate, said reflectors and reflector plate having aligned openings, lamp receptacles carried by the flrst plate and adapted to extend through said openings, means for adjusting said flrst plate, said housing having air vents in its top and bottom at opposite sides of said plates, said plates having ports adjacent said reflectors for passage of air therethrough, and a circulating fan in said housing adapted to circulate air through said bottom vent, ports and top vent respectively.

2. In an illuminating device, an open front housing, a plate mounted therein and adjustable from front to rear of said housing, a reflector plate forward of the first plate, reflectors carried by said reflector plate, said reflectors and
